CHARLES E. INCE, OF PROVIDENCE, RHODE ISLAND.

FILTER.

SPECIFICATION forming part of Letters Patent No. 555,773, dated March 3, 1896.

Application iiled March 14, 1895.

To LZZ whom it may concern.'

Be it known that I, CHARLES E. INCE, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Filters; and I do herebyT declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to water-filters-that is, to the class of portable filters adapted to be removably secured to the usual water cocks or faucets connected with the domestic water-service and it consists essentially in a separable filter provided internally with a double series or sets of filtering mediums separated from each other vertically to form an intermediate chamber and having the cap or inlet member provided with a diffuser or separator adapted to break the force of the waterbefore it comes in contact with the upper filter-bed, all as will be more fully hereinafter set forth and claimed.

I am well aware that iilters of the class adapted for domestic or household use have been devised prior to my invention, but such former filters have usually been quite complicated in construction and correspondingly expensive, and even requiring considerable skill on the part of the user to properly recombine the several parts after they have been taken apart and cleansed.

The object I have in view is to produce a water-filter which is simple in construction and also inexpensive. Moreover, it can be readily taken apart and quickly cleaned, or,

. if desired, the :filtering-beds, when foul or charged, maybe removed and clean iltering material substituted without the possibility of getting the various parts misplaced.

ly means of my improved filter the force of the infiowing water is broken and distributed or diffused over the entire surface of the top screen. The device is adapted to collect any comparatively large piece or mass of foreign matter or substance, thereby pre- Serial No. 541,763. (No model.)

venting injury to the screen and practically unaffeeting the efficiency of the lter.

Another advantage of' my device isI that the water iirst passes through an upper or initial filter-bed, thence into an intermediate chamber, and from the latter the water ilows through the bottom filter-bed into any vessel or receptacle.

In the accompanying drawings, Figure 1 is a side elevation in partial central section showing my improved filter, and Fig. 2 shows a modified form of the joint.

A, referring to the drawings, indicates my improved ilter complete. The body or casing ot is enlarged at its upper end and is tapped, as at a', to receive the screw-threaded rim or circular flange c of the cap or cover member c. The casing is cylindrical intermediate 0f the end portions and is provided with a seat n, to which is secured in any suitable manner the bottom screen or strainer, sa. The bottom end of the casing is contracted in diameter to form the outlet-nozzle d. The said cap c is provided with a central inletnozzle, b, adapted to be secured to a water faucet or cock in any suitable manner. Within the cap c is secured a cage g, the same forming a coarse strainer and diffuser. As drawn, it consists of a series of upwardlybent wires radiating from a common center and located directly below and communicating with the main inlet-passage. The lower end or face of the cap-rim c' is arranged to snugly engage a flexible packing m, let into the adjacent portion of the casing or shell a. The cap-rim is further adapted to engage the upper screen, s, the former being reduced in diameter and extending downwardly at c2 into the barrel-chamber for the purpose.

The several strainers or screens consist of suitably perforated or reticulated disks of metal. The bottom one, s3, is secured to the seat n, as before stated. The upper one, s, is in contact with the cap-rim, and the upper and lower intermediate strainers, s 82, respectively, are joined together by a central tie t, the space between them constituting an intermediate chamber w. I may state that the disks s s form the upper series of strainers and s2 s3 the lower series. Interposed between each of said series of strainers is located a bed of IOO aluminum, brass, &c. The parts a and c may be made of cast-iron or of brass and finished in any suitable manner.

While I have represented the two parts composing the shell of my improved filter as screwed together, it is obvious that other wellknown means may be adopted for the purpose-that is to say, they maybe made to interlock by what is termed a bayonet-fastenin g. The form of the rim c' of the cap c and the adjacent part of the shell a may be modiiied, as shown in Fig. 2, wherein the upper intermediate strainer, s', is slightly enlarged in diameter and rests on a small seat u2, the top strainer, .s,bein g still further enlarged and held snugly between the face of said rim and the packingseat. I prefer the arrangement shown in Fig. l, wherein the several interior parts are practically interchangeably alike.

In use my improved iilter A is suitably secured, say, to the service-faucet.

(Partly indicated by the dotted lines in Fig. l.) Now upon opening the faucet or cock the pressure forces the water into the upper chamber formed within the cap c and at the same time upon its striking the cage g the water is diffused over the surface of the top screen, s. The water next passes through the upper filter -bed, thereby mechanically separating from the fluid more or less of any foreign matter present, and thence into the intermediate chamber w. From the latter the water iiows through the lower filter-bed, which in turn serves to practically arrest and retain any impurities which may have passed the top iilter-bed. The clear or puriiied water is drawn off at the outlet-nozzle d, located at the bottom of the filter.

I claim as my invention and desire to secure by United States Letters Patent- In a filter, the combination of the casing a having the seat n, said casing being of undiminished diameter above said seat, the strainer s3, the strainers s, s2 integrally connected by the supporting-,post t the strainer s, the upper and lower iilter-beds between the strainers, and the screw-cap 4forlthe-iilter, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.

CHARLES E. INCE.
